When a security such as a bond is sold between interest payment dates, the seller is eligible to some fraction of the coupon amount.

One first calculates the directional movement (+DM and -DM): UpMove = today's high − yesterday's high DownMove = yesterday's low − today's low if UpMove > DownMove and UpMove > 0, then +DM = UpMove, else +DM = 0
